I took the approach of Subclassing ConfigParser to support multiline
values without leading white-spaces, but am struct at which position
in _read I should modify to accomodate the non-leading whitespace
based multiline values.
I can guess, this portion in the _read function will require change,
any change to this affects the whole of parsing. :-( Can someone who
has done this before or understands ConfigParser better help me?
